The Keysight 70810B is a modular lightwave receiver module designed to extend the measurement capabilities of the Keysight 70000 series modular measurement system (MMS). It integrates an optical attenuator, broadband photodetector, microwave preamplifier, RF amplifier, and optical power meter into a single instrument platform for optical signal analysis in RF and microwave test environments.
– Technical Specifications
• Frequency Range: 100 kHz to 22 GHz
• Wavelength Range: 1200 to 1600 nm
• Detected Modulation Bandwidth: 100 kHz to 22 GHz
• Optical Attenuator: up to 30 dB in 1 dB steps
• Form Factor: Modular unit for rack-mount or benchtop integration within Keysight 70000 MMS chassis
– Key Features
• Integrated optical attenuator with precise 1 dB step control
• Broadband photodetector with built-in RF amplification
• Microwave preamplifier for signal conditioning
• Optical power meter for inline power measurement
• Designed for Installation Category II environments
• Operates in Pollution Degree 2 installations
• Requires adequate ventilation; forced convection may be necessary in high-power cabinets (>800 watts)
– Typical Applications
• Optical communication system testing
• Fiber optic characterization and measurement
• RF and microwave signal analysis over optical carriers
• Optical-to-electrical conversion and detection
• Research and development in lightwave systems
– Compatibility & Integration
The 70810B operates exclusively within the Keysight 70000 series modular measurement system, using proprietary MMS connectors and data buses. It enhances spectrum analyzer and network analyzer capabilities for integrated RF/optical test workflows.
Product Status: Discontinued as of April 30, 2006. The N4377A Lightwave Detector is listed as a potential replacement.
